Comparative analysis of second harmonic generation in ordinary and backward-wave settings is presented. Extraordinary properties of frequency doubling nonlinear optical reflectivity and pulse shaping through phase matching of ordinary and backward electromagnetic waves in the nanowaveguides with mixed negative/positive spatial dispersion is demonstrated with numerical simulations.
Extraordinary properties of nonlinear-optical propagation processes are investigated which involve electromagnetic or elastic waves with negative group velocity. Nanostructured materials that support such waves are described. Nonlinear-optical energy transfer between contra-propagating short pulses are investigated and prospective unique photonic devices are discussed.
Extraordinary properties of short-pulse second harmonic generation in a frequency double-domain positive/negative index metamaterial are investigated and shown to appear in striking contrasts with those of their counterparts in ordinary materials. A metamaterial made of carbon nanotubes is proposed which supports coexistence of ordinary fundamental and backward second harmonic electromagnetic waves...
Several nonlinear-optical coupling schemes in double domain positive/negative index metamaterials are proposed, which include ordinary and backward electromagnetic waves. One of them is investigated in the context of the applications to compensating strong losses inherent to plasmonic metamaterials and to design of novel ultracompact photonic devices for optical sensing and data processing. Each of...
The possibility of creation of remotely all-optically controlled microchip is described based on coherent nonlinear-optical energy exchange between ordinary and backward electromagnetic waves in negative-index metamaterials.
